North is up in this
image. This field lies within the constellation of Serpens. Sharpless 64 is
central in this image. It is obscured by the dust of the Great Rift of the Milky
way (stretching from Cygnus to Centarus) Much of the image shows a portion
of the Rift (Milky Way star field is seen on the left and right of the image).
The Sharpless 64 emission is energized by stars in the W40 star forming region
(not well seen due to the obscuring dust of the Rift. There are many catalogued
dark nebulae in this image (60 listed in SIMBAD in TGU, Dobashi, and Lynds Dark
Nebula catalogs). Some of these objects as well as a few
of the bright stars are identified
in the annotated image.
Horizontal FOV is 120'
